What are thermoplastic polymers? Give an example.

Explanation

Thermoplastic polymers: Those polymers (linear or slightly) branched long chain molecules) which are capable of softening on heating and hardnening on cooling are called thermoplastic. These polymers posses intermolecular forces of attraction intermediate between clastomer and fibres.Example are polythene,polyvinyI chloride,polystyrene,etc.
Thermostting polymers: Those polymers (cross-linked or heavily branched molecules) which on heating do not soften and cannot be remoulded are called thermosetting polymers. On heating they undergo extensive cross-linking in moulds and becomes infusible, Example are bakelite formaldehyde resin etc.
